Single-Motor vs. Dual-Motor Power Steps: What's the difference, and which is more reliable?
It ultimately comes down to an engineering choice between extreme localized thrust and long-term mechanical stability. We engineered our power steps to prioritize the lowest possible failure rates over years of daily use.
Here is an objective breakdown of the two designs:
The Dual-Motor Approach
How It Works
Uses two independent motors on a single step. Each motor drives its own linkage, providing direct, localized thrust on both sides of the board.
The Trade-off
While it offers high independent direct drive, it introduces a major structural vulnerability: Electronic Synchronization. For the step to deploy smoothly, dual-channel controllers must keep both motors running at the exact same speed.
The Single-Motor Approach
How It Works
Uses one heavy-duty, high-torque motor to transfer torque through a high-strength board to the passive linkage, achieving synchronization of both linkages.
High Synchronization
Because there is only one power source, there are no issues with step board jamming or non-synchronization due to power source differences.
Lower Failure Rate & Simplified Wiring
By using a single high-torque motor, optimizing the ECU control algorithm, and simplifying the wiring, we drastically reduce the number of electronic components.
Engineered to Last. Built to Work.
When it comes to power steps, the simplest design that still gets the job done is almost always the most reliable. We chose the single-motor approach for one reason: it fails less.
